Patrick Rothfuss is holding a raffle again this holiday season, this year with a snazzy new name. Worldbuilders! All proceeds (and more, 50% of donations are being met) go to Heifer International. If you either like helping people, like giving people fuzzy animals, or like SF/F books, I would highly recommend donating money to the raffle.
Once again, if anyone wants to give me a Christmas present, donate some in my name/send me the prizes.
